Things you should take into consideration when calculating
size of conductor to be used on an installation.
1. Type of material been used. (i.e. copper / aluminium)
2. Length of conductor
3. Voltage Drop
4. Situation been used. (Enclosed, Unenclosed, Etc.)
5. Current Rating of Conductor (Current carring capacity)
6. Temperator Co-effiecient
These are some typical thing to look for.

Answer / adil akhtar

we can find the size of conductor either aluminum or copper
by the formula
R = P*l/A
whare R is resistance of conductor
......P is resistivity of conductor
......l is length of conductor
......A is area of crossection
and we can find the length of conductor or area of
crossection by this formula....
